Routine
-
double VRfDotProd (const float x1[], const float x2[], int N)
Purpose
-
Dot product of two float arrays (double result)
Description
This routine calculates the dot product of two float arrays x1 and x2. The
dot product is calculated internally as a double and returned as a double
value.
N-1
VRfDotProd = SUM x1[i] * x2[i] .
